which class ? Can u tell me.

Answer 2

Step-by-step explanation:

4x + ay + 8 = 0   ----------- (1)

2x + 2y + 2 = 0   -----------(2)

a₁ = 4 , b₁ = a , c₁ = 8

a₂ = 2 , b₂ = 2 , c₂ = 2

For unique solution,

a₁ / a₂ ≠ b₁ / b₂

4 / 2   ≠  a / 2

      2  ≠  a / 2

2 * 2  ≠  a

      a  ≠  4

So, a is any value except 4
